Description

Technical Field

[0001] This utility model relates to the field of solid material filtration technology, and in particular to a solid material filtration device for wastewater treatment in waste incineration. Background Technology

[0002] In people's daily lives, a large amount of waste is inevitably generated. If this waste is not effectively treated, it will greatly affect people's living environment and even threaten their health. At present, incineration is one of the main ways to dispose of waste. However, in the process of incinerating waste, in addition to causing secondary environmental pollution, it will also waste resources and energy. Therefore, in waste treatment, in order to remove suspended solids (SS), colloidal particles, grease and some pollutants (such as heavy metals and organic matter) from wastewater and ensure the stable operation of subsequent treatment units (such as biochemical reactions and deep purification), waste incineration plants usually use solid matter filtration devices to filter solid matter in wastewater.

[0003] However, existing solid matter filtration devices are not convenient to clean up after filtering solid matter, which can lead to the accumulation of filtered solid matter and affect subsequent filtration, making them inconvenient to use. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose a solid waste filtration device for wastewater treatment in waste incineration, so as to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides a solid waste filtration device for wastewater treatment in waste incineration, including a wastewater treatment pipe for guiding wastewater generated during waste incineration, a filtration pool for treating wastewater generated during waste incineration located below the wastewater treatment pipe, a filter plate assembly for filtering solids arranged at an incline inside the filtration pool, a baffle plate for blocking wastewater located at the lowest point of the filter plate assembly, a collection pool for collecting solids fixedly installed at the bottom of the baffle plate, a guide filter plate for secondary filtration of solids located inside the collection pool, a drainage rack for guiding wastewater located below the guide filter plate, and a detachable baffle for discharging solids located below the drainage rack.

[0006] Preferably, one end of the filtration pool is provided with a discharge trough for supporting and fixing the filter plate assembly, and the top of the filtration pool is provided with a fixing rod for supporting the sewage treatment pipe.

[0007] The above technical solution is adopted: the discharge trough at one end of the filtration pool is used to support the end of the filter plate assembly, and the top fixing rod (stainless steel) suspends and fixes the sewage treatment pipe to ensure that the sewage falls vertically into the filter plate. The inner wall of the pool is treated with epoxy resin for corrosion protection, which is resistant to acid and alkali corrosion and can effectively contain the filtered sewage, providing a buffer space for subsequent treatment.

[0008] Preferably, in any of the above embodiments, the filter plate assembly includes a water-blocking bracket for support and a filter plate for filtering solids. The water-blocking bracket is fixedly installed at the top of the filtration pool. One end of the water-blocking bracket is fixedly installed with a filter plate located inside the filtration pool. The end of the filter plate away from the water-blocking bracket is fixedly installed with the filtration pool and its end face is flush with the end face of the filtration pool. The top of the water-blocking bracket is configured with a U-shaped structure. The sewage treatment pipe is located on one side of the water-blocking bracket. The outlet of the sewage treatment pipe is extended to a sufficient length so that sewage falls through the filter plate into the interior of the filtration pool without entering the collection tank. Only the filtered solids fall along the filter plate into the interior of the collection tank.

[0009] The above technical solution is adopted: the water-blocking bracket (Q235 steel) is fixed at the top of the filter pool, supporting the filter plate to form a filter slope. The filter plate is made of high-strength polyester mesh. After the sewage is discharged from the sewage treatment pipe, it flows through the filter plate. Solids are intercepted and slide down the slope, while sewage enters the filter pool through the mesh, thus improving the filtration efficiency. The U-shaped structure of the water-blocking bracket can block splashing water and prevent sewage from overflowing.

[0010] Preferably, in any of the above embodiments, the baffle plate includes a lifting cylinder for driving and a baffle for blocking solids. The lifting cylinder is fixedly installed inside the collection tank, and the top of the lifting cylinder is fixedly installed with a baffle that moves inside the collection tank. The baffle is in contact with the end face of the filter plate and the end face of the filtration tank.

[0011] The above technical solution is adopted: the lifting cylinder drives the baffle (made of stainless steel) to rise and fall, and fits with the end of the filter plate and the end face of the filter water tank. During filtration, the baffle rises to prevent sewage from flowing into the collection tank along with the solid material. When the solid material needs to be cleaned, the baffle falls down and the solid material falls into the collection tank under the action of gravity, realizing solid-liquid separation. The cylinder response time is set, and automatic start and stop can be realized through timed control.

[0012] Preferably, in any of the above embodiments, the collection tank and the filter water tank are fitted together, and one end of the bottom of the collection tank is provided with a guide groove for engaging and fixing the disassembly baffle.

[0013] The above technical solution is adopted: the material collection tank (welded integrally with the water filtration tank) is attached to the lower end of the filter plate, and the bottom outlet channel is adapted to the detachable baffle to form a closed cavity to temporarily store solids, reduce the adhesion of solids, and ensure that solids are concentrated and accumulated above the outlet channel for easy subsequent cleaning.

[0014] Preferably, in any of the above embodiments, the guide filter plate includes a guide fixing seat for support and a filter press fixing plate for squeezing and filtering solids. The guide fixing seat is fixedly installed at one end of the collection tank near the filter water tank. An inclined filter press fixing plate is fixedly installed at the top of the guide fixing seat. The filter press fixing plate is located below the filter plate. The drain frame is fixedly installed at one end of the collection tank. One end of the drain frame is fixedly installed with the filter water tank.

[0015] The above technical solution is adopted: the guide fixing seat (carbon steel material) supports the filter press fixing plate and is located directly below the filter plate. When the solid material falls, it impacts the filter press fixing plate, and the residual water flows through the mesh into the drain rack (PVC material) and flows back to the filter water tank to realize water circulation. The surface of the filter press fixing plate is coated with polytetrafluoroethylene to reduce the adhesion of solid material and improve the secondary filtration efficiency.

[0016] Preferably, the disassembly baffle includes a sealing plate for locking and sealing the collection pool, a fastening spring for support, and a fastening block for locking the sealing plate. The sealing plate is locked to the bottom of the collection pool, and a fastening spring is fixedly installed inside the sealing plate. A fastening block that moves inside the sealing plate is fixedly installed at one end of the fastening spring.

[0017] The above technical solution is adopted: the sealing plate (stainless steel material) is engaged with the discharge channel of the collection pool, and the internal fastening spring pushes the fastening block (wedge structure) to be embedded into the pool body slot, generating a clamping force to achieve a seal. When cleaning, press the block to compress the spring, and the sealing plate can be pulled out to discharge solids. The sealing gasket (nitrile rubber) ensures that there is no leakage when closed.

[0018] Wastewater flows into the filter plate assembly through the wastewater treatment pipe. The filter plates trap large solid particles. The wastewater enters the filtration pool, and the solid particles slide down the inclined surface of the filter plates to the end. The baffle plate rises to block the wastewater, and the solid particles fall under the action of gravity. The solid particles impact the filter press fixing plate that guides the filter plates. After secondary filtration, the water flows back through the drainage frame, and the solid particles fall into the collection pool. The baffle plate is lowered by timed (or manual) control. The baffle plate is opened to discharge the solid particles. After cleaning is completed, the baffle plate is reset. The lifting cylinder is linked with the timer and is set to lower once at a set time to ensure that the solid particles fall into the collection pool in time.

[0019] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0020] 1. A collection tank for storing filtered solids is set up on one side of the inclined filter plate assembly for wastewater filtration. Gravity guides the filtered solids to the collection tank along the inclined angle of the filter plate assembly. A baffle plate that can fit against the lowest point of the filter plate assembly and can be raised and lowered is set at one end of the collection tank. The baffle plate blocks the wastewater falling with the solids, allowing the accumulated solids to fall into the collection tank. This effectively collects and treats the filtered solids, prevents the accumulation of solids from affecting subsequent filtration, and improves the stability of the filtration device.

[0021] 2. Inside the collection tank, a guide filter plate is installed to perform secondary filtration of solids. Gravity causes the accumulated solids to fall and hit the guide filter plate. During the impact, the water in the solids is separated and flows into the interior of the guide filter plate and enters the filtration water tank along the drainage frame.
